Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564410, here are decompositions:

19 + 31564391 = 31564410
23 + 31564387 = 31564410
79 + 31564331 = 31564410
83 + 31564327 = 31564410
89 + 31564321 = 31564410
139 + 31564271 = 31564410
149 + 31564261 = 31564410
167 + 31564243 = 31564410

Showing the first eight; more decompositions exist.
